Ok here’s just a little rhyme and instructions for you to remember how to answer these questions
1.Stack it
(Just remember the higher number always goes on top negative or positive)
Same sign Add (+) and keep
Different sign Subtract(-)
Keep sign of higher number and then you’ll be exact
For some examples here you go
1. (-8) + 12
12
+-8
——-
4
2. 15 + -27
-27
+15
——-
12
Hope this helps :)
